Geeky Valentine Gifts?

WouldUBMine asks: "My valentine is fairly geeky and instead of boring roses or some other generic gift, I am looking for something that may be a little cooler or at least interesting. The only site I know of that targets geeks is www.thinkgeek.com and they don't stock any valentine-specific products. Does anyone have any good ideas?" Valentine's Day tends to be just another day for me (and I'm sure a few of you are in the same boat). For those of you who still take part, what places, both on and offline, have gifts that communicate those special feelings for your favorite Geek, in just the right way?
